Table 1. Truth Table
The tristate conditions and the fault status are reset using D1 or D2. The truth table uses the following notations: L = Low, H =
High, X = High or Low, and Z = High impedance (all output power transistors are switched off).

Notes:
26. In the case of an undervoltage condition, the outputs tristate and the fault status is SET logic LOW. Upon undervoltage recovery,
fault status is reset automatically or automatically cleared and the outputs are restored to their original operating condition.
27. When an overcurrent or overtemperature condition is detected, the power outputs are tristate latched-OFF independent of the input
signals and the fault status flag is SET logic LOW.
